I0 all whom it may concern:

Bc it known that I, Jnnns EDWARD W. PooLimN, a citizen of the UnitedStates, residing at New York, in the county and State of New York, haveinvented certain new and useful Improvements in Desk Attachments, ofn'hichthe following is a specification.

My invention relates to certain improvements in desk attachments forchairs and other articles of furniture for affording facilities forwriting, reading, or for other purposes Where an ordinary desk might bynecessary; and my improvements consist, generally, in a novelconstruction and arrangement of devices whereby the desk may be adjustedat any desired inclination, and the top be swung off from the box orcase of the desk, all as will be fully hereinafter set forth.

In the accompanying drawings, which serve to illustrate my improvements,Figure l is an end. view, partly in section, representing my deskattachment as applied tothe rail of a chair. Fig. 2 is a top View of thedesk, showing the receptacle uncovered, and Fig. 3 is a sectional Viewof a modified form of the device for effecting the adjustment of thedesk.

The-desk here shown consists of a box, a, which serves as the receptaclefor-holding the necessary Writing materials, and a top or cover, Z), forthe same.

The desk is capable of being set at any anglo or inclination desiredwith extreme nicety by the following means: To the under side of the boxc is secured, by means of screws or otherwise, the brackets c c, whichare constructed with a socket which forms the bearing for a shaft, c.The inner surface of this socket or bearing d is beveled or tapering, asshown at f, and the ends of the shaft c are enlarged and correspondinglybeveled, as seen at g. 71` is a rod that passes through the shaft c andits bearings, and is secured therein by a head, i, on one end andthumb-nut j and washer j on the opposite end. On the shaft e is provideda plug, K, which tits into a socket formed in the end of the arm n,which arm is connected in a similar manner to an arm, in., on theupright standard o. The central rod,

lz, as shown in Fig. l, is provided with a threaded end to receive thethumb-nut j. XV hen the desk is set at the desired position orinclination, the thumb-nuty` is screwed up tightly against the bracketc, and the shaft and bracket-s are clamped firmly together.

In Fig. 3 a modified construction of the rod 7i is shown. Here the rodis shown as having a screw-threaded end, 7L', which screws into athreaded socket in the bearing or hanger c. The opposite end of the rodis constructed with a thumb-piece, p.

The top or cover b of the desk is arranged to turn on a pivot in theposit-ion shown in Fig. 2, leaving the receptacle a. uncovered at thetop. To the under side of the cover b is secured by plate c a pin, q,which passes through a block, fr, arranged in the front part of thereceptacle c, and is secured on the outside thereof by means of a nut,s, and Washer t. A stop-pin is arranged on the front of the receptacleto limit the movement of the cover b, and a catch, w, confines it inplace when it is in its normal position.

The desk is supported by the standard o, which is connected to the chairby a clamp, y. Vertical adjustment of this standard is eifeeted by athumb-screw, z. On its upper end is provided a socket, o', for thereception of plug a' on the arm m.. A similar plug and socket connectsthe arm m With the upper arm, n.

Vhat I claim as my invention, and desire to secure by Letters Patent,is-

l. In an adjustable desk, the combination, with the case or box and asuitable support, of brackets provided with sockets, a shaft journaledin said brackets, and a rod connecting the brackets'and passing throughthe shaft, and provided with a threaded end and thumbnut, as and for thepurpose set forth.

2. The combination, with the box c and its support, of the brackets e c,having beveled sockets d, shaft e, provided with beveled journals, androd a, passing centrally through said shalt and secured by a thumb-nutor equivaient device, as and for he purpose set forth.
